The game features 3D weapons, including fire-off lock-ons, rockets, multi-fire swarmers, and plasma cannons. The player must use all these weapons when facing deadly air and ground forces in desert and volcanic wastelands, castle hallways and chambers, and gothic tower airships.
There are no saving or loading features. Instead, a password is presented each time a level is completed. In 2007, Incognito Entertainment remade the title as a multiplayer-only PlayStation 3 game.
